Back in the early 90's I had a full beard. Decided it had to go. Got out my battery charged shaver. First I had goatee. Then a soul patch. Then just a moustache. Being clever I decided Hitler moustache! 20 mins later after walking about like John Cleese I went back to shave it off. Battery had run out. Could I find another battery? No? Could I find a razor? No. Had to walk through Adamsdown with a Hitler moustache to buy new batteries from the "corner" shop.
